The saddle, S0 called, provides a means of .tensioni-ngthl rolls as is well known to those familiar with the art of spinning. 1 p

Ordinarily; these rolls are provided-With snitable end bearings anduwithtia center bearing 'portion.'- Upon the latter rests 5-the saddle which bing held down as "by: a stir rilp' and weight, causesthe 'up'pensetforzthe floatin rolls ta bear with as' greater or enses upon the lower xst bf rollsiy.

The saddle part 10 has bearing surfaces upon its under side so disposed that they will fit upon practically any arrangement of rolls' 1 d the part 11 has a bearingsurface which fits the forward roll. r

In the"upper side of the part 10, which might well be termed the female part, there is a longitudinal groove of slot 15, which ex tends from end to end of the saddle part.

'Upon the under side of the part 11 which may be called the male part 13 a centrally disposed dependent fin or web 16 which fits into the roove 15 of the female part. This fin 16, 0% the male part is of considerable length and obviously when the parts are in place holds them against lateral displacement. f 30 The main bearing between the malepart 11 and female part 10 is at 17, u, on the under side of the male part at'ei erside of its fin l6 and at 18, 19 upon the upper sideof the female part10at either side of its groove 15.

It is quite obvious that the male and fe male parts may be adjustedto any desired degree with reference to each otherxin a lon 'tudinal direction; the fin 16 resting in di, erent positions along the groove 15.

Any adjustmentwhi'ch is made does not revent the necessary freedom of movement of the male and female parts to permit them to adjust themselves ,to their respective rolls witha proper dispcsiticn di tension.

Such a material provides lubrication between the saddleiparts and the rolls and between the male and femaleparts of the saddle.

I may, in lieu of the material described in my prior patents, use awood or fiber 'impregnated through and thronghwith graphite carried with otherlubricating materials.

The exact form and design of the parts may be deviated from to any desired extent without departing from the spirit or intent of the intention which, in the main, contemplates an adjustable saddle, having practically an unlimited longitudinal adiustment, to fit various combinations of rolls, and with means {for preventing lateral or other separation at the-parts, when in use; together with adjustabihty of tension upon theseweralrolls ii Y t, 1g a -Wliat 'l claim'tis y invention land desire tosecureby'LettersPatefitist 1.
